Two climbers have died on a mountain in New Zealand after being trapped for two nights in high winds, police said on Monday.

Hiroki Ogawa, 31, from Japan, and Nicole Sutton, 29, from New Zealand, were part of a group of climbers who reached the summit of Mount Taranaki on Saturday before encountering bad weather on the descent, police said.

Two other climbers in the group made it to safety after spending a night on the mountain.

Ogawa and Sutton dug themselves into the snow as best they could and had been texting police until Sunday night, but poor conditions prevented rescuers from reaching the pair until early Monday morning.

Police said that Sutton was still alive when rescuers reached them but soon became unresponsive.

Poor conditions forced rescuers to leave the bodies on the mountain on Monday. They plan to try to recover them Tuesday.

Sutton's parents told reporters that their daughter and Ogawa were in a relationship and had thought they might one day marry.

Ogawa was a research fellow at the University of Auckland's school of environment.
